I am going to graduate from Department of Computer in Huabei University in June next year. I am very eager to enter the Graduate School of your university next fall to study applied computer for Ph.D. degree.
I would appreciate it very much if you would send me a graduate catalog of your university and any other necessary information, and also a set of application forms for admission. Thank you for your kind assistance.
I am writing in the hope that I may obtain an opportunity to further my study in Applied Physics toward Master degree in your university.
My name is Li Jin, an undergraduate student of the Department of Applied Physics, Huabei University. Next year in the summer, I will graduate and get my B.S. degree. I plan to continue my study and research in this field. I chose Boston University because there are a congenial team of researchers, an array of databases and research projects in your school of Physics. I believe my interests are extremely congruent with the strengths of the school. And my solid academic background will meet your general entrance requirements for graduate study.
I will appreciate it very much if you could send me the Graduate Application Forms, the Application Form for Scholarships/Assistantships, and other relevant information. My mailing address is shown on the top of this letter.
I am looking forward to hearing from you soon.
